Six feather mite species presently referred to the genus Proterothrix Gaud, 1968 (Proctophyllodidae: Pterodectinae) were briefly described without being drawn by a French zoologist Édouard Louis Trouessart in end of 19th century. The type material used for description these is still preserved Muséum National d'Histoire Naturelle (Paris, France). Based on this material, we provide detailed redescriptions, according modern format pterodectine mites, following species: diminuta (Trouessart,...

Abstract The B ukovina blind mole rat S palax graecus is the westernmost representative of genus and one least known E uropean mammals. As currently understood, species contains three isolates on both sides south‐eastern C arpathian M ountains. Our focus was rats from north‐eastern R omania adjacent U kraine, i.e. nominal subspecies Spalax Topachevskii 1976. Phylogenetic reconstruction based 1140‐bp‐long cytochrome b sequence revealed a sister position against N annospalax . Pairwise K imura...
